Application filed July 3, 1920. Serial No. 393,961.

To all whom t may concern Be it known that I, HAROLD P. DEELY, a citizenof the United States, residing at vWaterbury, in the ycounty of NewHaven and State of Connecticut, have invented certain new and usefulImprovements in Swivel-Blocks for Heading-Machines, of which thefollowing is a specification.

The present invention relates to cold heading rivet machines andconsists in the combinations and arrangements of elements hereinafterdescribed and particularly set forth in the accompanying claims.

The invention has for its purpose to provide a swivel blockV formachines of this character which will permit of a simple and eiiicientmeans for conveniently adjusting the operative tools of the machine inorder that each tool may be moved into its proper position withoutaffecting the correct position of the other tool or tools.

A further purpose of the invention is to produce an adjustable swivelblock which will do away with several parts now employed on cold headingrivet machines to the more simple in construction, easy and convenientfor operation, and to reduce the cost of constructing the machine as awhole.

The invention is disclosed by way of illustration in the accompanyingdrawings wherein- Figure 1 is a longitudinal sectional view of thedevice mounted on a machine;

Fig. 2 is a front elevational view of the swivel block holder;

Fig. 3, a top plan view thereof;

Fig. 4, a side elevational view of lthe same;

Fig. 5, a front elevational view of the swivel block holder per se;

and

Fig. 7 is a rear elevational view of the swivel block.

Referring to the construction further detailed and wherein likereference characters designate corresponding parts in different viewsshown, 8 is a fixed part of the heading machine used for the purpose ofillustration and 9 indicates the die held therein. The reciprocatinggate 10 has suitably mounted thereon a lock 11 having mounted thereonthe swivel block 12, and 13 indicates the usual stop screw having a seto r locking nut 14 as shown.

member 11 and Fig. 6, a side elevational view thereof,

The punch holder 12 is constructed with an integrally formed pivot tofit within the recess 15 in thev swivel block 16, and which block inturn is mounted to rotate within the recess or chamber 17 formed in thefront face of the swivel block holder 11.

Mounted on the front of the punch holder 12 is a pair of punches 18 and19 of any usual construction and adapted to be locked in position by thebolts 2O and 21 respectively; and said dies are adapted to besuccessively brought into alined position with respect to the die 9 aswith machines of this type The means for securing the punch holder 12 totransfer slide or the block holder 11 consists of two bolts 23passingthrough the having heads 24 countersunk therein, and each' ofsaid bolts is tted with an ordinary tightening nut 25 screw threadedthereon as shown.

The device for imparting ne adjustment to the punch holder after thesame has been initially secured to the block holder 11 consists of apair of threaded pins or screws 26 (one being apertures 27 that enterthe openings 28 through which the bolts 23 pass, and by means of thesescrews (adjusting screws 26) said punch holder may be slightly shiftedfrom one position to another and such adjustment secured by tighteningsaid pins 26 against the bolts 23 as will be understood.

It is obvious that those skilled in the art may vary the details ofconstructionand arrangement of parts without departing from the spiritof my invention; therefore I do not wish to be limited to such featureseX- cept as may be required by the claims.

Having thus described my invention what is claimed as new and tected byUnited States Letters Patent is 1. A die block holder for headingmachines comprising a supporting member formed with a recess therein, anapertured block pivotally mounted within said recess, a swiveled dieholder having a projection fitted within said apertured block, bolts forclamping the die holder to said support,

and screws coperable with said clamping bolts for effecting angularadjustment of the die holder, substantially as set forth.

' 2. A die holder for heading machines comprising a supporting memberadapted Patented May 3, 1921. j

pin 14 adapted desired to be proshown) fitted within the threaded i tobe adjustably mounted on the machine, and formed With a recess therein,an apertured block pivotally mounted in said recess, a swiveled dieholder having an integral portion pivotally mounted Within saidapertured block, a pair of bolts clamping the die holder to saidsupport, and a pair of screws mounted on the die holder and coaotingwith each of said bolts for effecting angular adjustment of the dieholder, sub- 10 stantially asset forth.l

In testimony whereof I aflix my signature.

HAROLD P. DEELY.
